A new gene responsible for modulating bone mass in human has been discovered, reports a home-grown Canadian group of researchers, declaring a scientific breakthrough. This recent findings from the Institut de Recherches Cliniques de Montréal (IRCM) showed the emergence of a risk factor for developing osteoporosis, Science Daily says. Disorder in the hip bone at times lead patients to artificial implants and litigation over defective products. However, "Tennessee Man Files Pinnacle Hip Replacement Lawsuit".

Osteoporosis is results to the lowering in bone mass and changes in bone structure that leads to a weakening of the bones.  It is considered as a “silent” genetic disease which may lead to fractures and cause severe impact upon a person’s life, the osteoporosisadvice.com website says.

As a bone disorder, osteoporosis is also characterized by low bone mineral density and deterioration of bone tissue. It attacks some of the main areas in joints, especially in the hips and spine, as well as on the wrist, where fractures often occur. In all cases, the disease is caused by an imbalance between the formation and resorption of bone tissue, the Science Daily says.

The lead researcher, Dr. Jean Vacher, director of the Cellular interactions and Development and Resorptions, says that the overall objective of their research is to understand the molecular and cellular mechanisms that identify the balance between bone formation and resorption. He added that osteoblasts are responsible for making bones and work in synergy with osteoclasts, which reshape the bone, according to the Science Daily. This discovery shows the bone joint adjusting, regulating or adapting itself to a certain proportion.

Dr. Vacher further says that to gain insight into these complex mechanisms, his team is studying the role of new genes that influence osteoclasts and osteoblasts.

Researchers recently isolated a gene that modulates osteoclasts. They found, in mice, that a loss of this gene's function leads to a significant increase in the number of osteoclasts, thereby generating an even higher level of bone resorption, Science Daily says.

This gene has been identified as a novel modulator of bone mineral density in mice and humans. More importantly, new findings showed that the human gene could represent a new susceptibility factor for osteoporosis. Hence, this discovery will help identify individuals with greater predisposition to the disease who could benefit from preventive measure, Science Daily reports.

The best way to prevent osteoporosis from developing in your system is to  maintain an active and healthy  lifestyle through  regular exercise. Not only does exercise reduce the risk of developing osteoporosis but as well as lessen the risk of heart disease, high blood pressure and diabetes, netdoctor.co.uk website says, adding that it has a positive effect on mental well-being.

The types of exercise that are believed to be beneficial in preventing osteoporosis are weight-bearing, such as walking or aerobics. Research recommended daily intake of calcium for an adult is around 800mg. If this regimen is followed religiously by the people, the number of hip implants will decrease as well as the filing of Pinnacle Lawsuit.

For the duration of the childhood and adolescence, spirited sports activities such as basketball, may cause abnormal development of the femur in young athletes. Strenuous physical exertion may result to a deformed hip with reduced rotation and intense pain during movement, the Science Daily says.

Hip-straining sports activities may explain why athletes are more likely to develop osteoarthritis than more sedentary individuals, according to Dr. Klaus Siebenrock, who leads a medical research team from the University of Bern in Switzerland. Siebenrock and colleagues have published their work online in Springer's Journal  of Clinical Orthopaedics and Related Research.

Siebenrock and his colleagues discovered that osteoarthritis of the hip was more predominant in high-level athletes than in those who do not take part in regular sports, reports the Science Daily online resource.

Osteoarthritis of the hip was also linked to higher-intensity activities and greater physical loading of the hip, Siebenrock was quoted as saying. He distinguished that other surveys have discovered that male athletes, specifically those who play soccer and handball, and take part in competitive track and field events relating to  running and jumping, are at better risk of early osteoarthritis of the hip, the Science Daily says.

Siebenrock and teammates made a comparison of  the occurrence of cam-type hip disfigurement among elite athletes during childhood and adolescence and age-matched controls. Cam-type hip misshapenness is a ailment categorized by abnormal bone development on the head of the femur affecting the contact between the femur and the hip socket. They observed at the physical condition and wide array of mobility of 72 hips in 37 male professional basketball players and 76 hips in 38 controlled participants who had not participated in high-level sports.

They secured proof of irregularity at the head of the femur, leading to peculiar interaction between the femur and the hip socket, in men and adolescents who played in an elite basketball club since they were eight years old. As a result, internal hip cycle was lessened and hip motion were more likely to be painful. These changes became more noticeable after shutting of the femoral growth plate through late adolescence. Overall, the athletes were 10 times more likely to have impaired hip function than the controlled ones.

"Our data propose that this hip deformity is in part a developmental deformity, and its manifestation in young adulthood may be initiated by environmental factors such as high-level sports activity during childhood and around the time of closure of the femoral growth plate.

Given the part of the irregularity in deteriorating instabilities in the hip, morphological sorts of the femur resulting from dynamic sporting activity are a key element in the higher incidence of hip osteoarthritis observed in athletes," the research concluded. Because of this, more former athletes undergo hip replacement to relieve themselves from hip pains due to osteoarthritis. Though, instead of getting  the ease, hip implants usually may aggravate  the patient’s condition which may  lead into the filing a "Pinnacle lawsuit".
